With remarkable new suit, I'm sent to ladies' society (6,9)

Ross

I believe the answer is:

womens institute

I'm a little stuck... Click here to teach me more about this clue!

'ladies' society' is the definition.
The definition suggests a singular noun which matches the answer.

'with remarkable new suit i'm sent to' is the wordplay.
'new suit i'm sent to' can be anagrammed to 'WOMEN'S INSTITUTE'.
But, I'm unsure how this is indicated.

Can you help me to learn more?

(Another definition for womens institute that I've seen is " Group of females".)

I've seen this clue in The Daily Express.
